INTRODUCTION

Wireless communication networks are widely deployed to provide variouscommunication services such as voice, video, packet data, messaging,broadcast, and the like. These wireless networks may be multiple-accessnetworks capable of supporting multiple users by sharing the availablenetwork resources. Such networks, which are usually multiple accessnetworks, support communications for multiple users by sharing theavailable network resources.

A wireless communication network may include a number of base stationsor node Bs that can support communication for a number of userequipments (UEs). A UE may communicate with a base station via downlinkand uplink. The downlink (or forward link) refers to the communicationlink from the base station to the UE, and the uplink (or reverse link)refers to the communication link from the UE to the base station.

A base station may transmit data and control information on the downlinkto a UE and/or may receive data and control information on the uplinkfrom the UE. On the downlink, a transmission from the base station mayencounter interference due to transmissions from neighbor base stationsor from other wireless radio frequency (RF) transmitters. On the uplink,a transmission from the UE may encounter interference from uplinktransmissions of other UEs communicating with the neighbor base stationsor from other wireless RF transmitters. This interference may degradeperformance on both the downlink and uplink.

As the demand for mobile broadband access continues to increase, thepossibilities of interference and congested networks grows with more UEsaccessing the long-range wireless communication networks and moreshort-range wireless systems being deployed in communities. Research anddevelopment continue to advance wireless technologies not only to meetthe growing demand for mobile broadband access, but to advance andenhance the user experience with mobile communications.

DETAILED DESCRIPTION

The detailed description set forth below, in connection with theappended drawings, is intended as a description of variousconfigurations and is not intended to limit the scope of the disclosure.Rather, the detailed description includes specific details for thepurpose of providing a thorough understanding of the inventive subjectmatter. It will be apparent to those skilled in the art that thesespecific details are not required in every case and that, in someinstances, well-known structures and components are shown in blockdiagram form for clarity of presentation.

This disclosure relates generally to providing or participating incommunication as between two or more wireless devices in one or morewireless communications systems, also referred to as wirelesscommunications networks. In various embodiments, the techniques andapparatus may be used for wireless communication networks such as codedivision multiple access (CDMA) networks, time division multiple access(TDMA) networks, frequency division multiple access (FDMA) networks,orthogonal FDMA (OFDMA) networks, single-carrier FDMA (SC-FDMA)networks, LTE networks, GSM networks, 5^(th) Generation (5G) or newradio (NR) networks (sometimes referred to as “5G NR”networks/systems/devices), as well as other communications networks. Asdescribed herein, the terms “networks” and “systems” may be usedinterchangeably.

A CDMA network, for example, may implement a radio technology such asuniversal terrestrial radio access (UTRA), cdma2000, and the like. UTRAincludes wideband-CDMA (W-CDMA) and low chip rate (LCR). CDMA2000 coversIS-2000, IS-95, and IS-856 standards.

A TDMA network may, for example implement a radio technology such asGSM. 3GPP defines standards for the GSM EDGE (enhanced data rates forGSM evolution) radio access network (RAN), also denoted as GERAN. GERANis the radio component of GSM/EDGE, together with the network that joinsthe base stations (for example, the Ater and Abis interfaces) and thebase station controllers (A interfaces, etc.). The radio access networkrepresents a component of a GSM network, through which phone calls andpacket data are routed from and to the public switched telephone network(PSTN) and Internet to and from subscriber handsets, also known as userterminals or user equipments (UEs). A mobile phone operator's networkmay comprise one or more GERANs, which may be coupled with UniversalTerrestrial Radio Access Networks (UTRANs) in the case of a UMTS/GSMnetwork. An operator network may also include one or more LTE networks,and/or one or more other networks. The various different network typesmay use different radio access technologies (RATs) and radio accessnetworks (RANs).

An OFDMA network may implement a radio technology such as evolved UTRA(E-UTRA), IEEE 802.11, IEEE 802.16, IEEE 802.20, flash-OFDM and thelike. UTRA, E-UTRA, and Global System for Mobile Communications (GSM)are part of universal mobile telecommunication system (UMTS). Inparticular, long term evolution (LTE) is a release of UMTS that usesE-UTRA. UTRA, E-UTRA, GSM, UMTS and LTE are described in documentsprovided from an organization named “3rd Generation Partnership Project”(3GPP), and cdma2000 is described in documents from an organizationnamed “3rd Generation Partnership Project 2” (3GPP2). These variousradio technologies and standards are known or are being developed. Forexample, the 3rd Generation Partnership Project (3GPP) is acollaboration between groups of telecommunications associations thataims to define a globally applicable third generation (3G) mobile phonespecification. 3GPP long term evolution (LTE) is a 3GPP project whichwas aimed at improving the universal mobile telecommunications system(UMTS) mobile phone standard. The 3GPP may define specifications for thenext generation of mobile networks, mobile systems, and mobile devices.The present disclosure is concerned with the evolution of wirelesstechnologies from LTE, 4G, 5G, NR, and beyond with shared access towireless spectrum between networks using a collection of new anddifferent radio access technologies or radio air interfaces.

5G networks contemplate diverse deployments, diverse spectrum, anddiverse services and devices that may be implemented using an OFDM-basedunified, air interface. To achieve these goals, further enhancements toLTE and LTE-A are considered in addition to development of the new radiotechnology for 5G NR networks. The 5G NR will be capable of scaling toprovide coverage (1) to a massive Internet of things (IoTs) with anultra-high density (e.g., ˜1 M nodes/km²), ultra-low complexity (e.g.,˜10 s of bits/sec), ultra-low energy (e.g., ˜10+ years of battery life),and deep coverage with the capability to reach challenging locations;(2) including mission-critical control with strong security to safeguardsensitive personal, financial, or classified information, ultra-highreliability (e.g., ˜0.99.9999% reliability), ultra-low latency (e.g., ˜1ms), and users with wide ranges of mobility or lack thereof; and (3)with enhanced mobile broadband including extreme high capacity (e.g.,˜10 Tbps/km²), extreme data rates (e.g., multi-Gbps rate, 100+ Mbps userexperienced rates), and deep awareness with advanced discovery andoptimizations.

5G NR devices, networks, and systems may be implemented to use optimizedOFDM-based waveform features. These features may include scalablenumerology and transmission time intervals (TTIs); a common, flexibleframework to efficiently multiplex services and features with a dynamic,low-latency time division duplex (TDD)/frequency division duplex (FDD)design; and advanced wireless technologies, such as massive multipleinput, multiple output (MIMO), robust millimeter wave (mmWave)transmissions, advanced channel coding, and device-centric mobility.Scalability of the numerology in 5G NR, with scaling of subcarrierspacing, may efficiently address operating diverse services acrossdiverse spectrum and diverse deployments. For example, in variousoutdoor and macro coverage deployments of less than 3 GHz FDD/TDDimplementations, subcarrier spacing may occur with 15 kHz, for exampleover 1, 5, 10, 20 MHz, and the like bandwidth. For other various outdoorand small cell coverage deployments of TDD greater than 3 GHz,subcarrier spacing may occur with 30 kHz over 80/100 MHz bandwidth. Forother various indoor wideband implementations, using a TDD over theunlicensed portion of the 5 GHz band, the subcarrier spacing may occurwith 60 kHz over a 160 MHz bandwidth. Finally, for various deploymentstransmitting with mmWave components at a TDD of 28 GHz, subcarrierspacing may occur with 120 kHz over a 500 MHz bandwidth.

The scalable numerology of 5G NR facilitates scalable TTI for diverselatency and quality of service (QoS) requirements. For example, shorterTTI may be used for low latency and high reliability, while longer TTImay be used for higher spectral efficiency. The efficient multiplexingof long and short TTIs to allow transmissions to start on symbolboundaries. 5G NR also contemplates a self-contained integrated subframedesign with uplink/downlink scheduling information, data, andacknowledgement in the same subframe. The self-contained integratedsubframe supports communications in unlicensed or contention-basedshared spectrum, adaptive uplink/downlink that may be flexiblyconfigured on a per-cell basis to dynamically switch between uplink anddownlink to meet the current traffic needs.

For clarity, certain aspects of the apparatus and techniques may bedescribed below with reference to exemplary LTE implementations or in anLTE-centric way, and LTE terminology may be used as illustrativeexamples in portions of the description below; however, the descriptionis not intended to be limited to LTE applications. Indeed, the presentdisclosure is concerned with shared access to wireless spectrum betweennetworks using different radio access technologies or radio airinterfaces, such as those of 5G NR.

Moreover, it should be understood that, in operation, wirelesscommunication networks adapted according to the concepts herein mayoperate with any combination of licensed or unlicensed spectrumdepending on loading and availability. Accordingly, it will be apparentto one of skill in the art that the systems, apparatus and methodsdescribed herein may be applied to other communications systems andapplications than the particular examples provided.

While aspects and embodiments are described in this application byillustration to some examples, those skilled in the art will understandthat additional implementations and use cases may come about in manydifferent arrangements and scenarios. Innovations described herein maybe implemented across many differing platform types, devices, systems,shapes, sizes, packaging arrangements. For example, embodiments and/oruses may come about via integrated chip embodiments and/or othernon-module-component based devices (e.g., end-user devices, vehicles,communication devices, computing devices, industrial equipment,retail/purchasing devices, medical devices, AI-enabled devices, etc.).While some examples may or may not be specifically directed to use casesor applications, a wide assortment of applicability of describedinnovations may occur. Implementations may range from chip-level ormodular components to non-modular, non-chip-level implementations andfurther to aggregated, distributed, or OEM devices or systemsincorporating one or more described aspects. In some practical settings,devices incorporating described aspects and features may alsonecessarily include additional components and features forimplementation and practice of claimed and described embodiments. It isintended that innovations described herein may be practiced in a widevariety of implementations, including both large/small devices,chip-level components, multi-component systems (e.g. RF-chain,communication interface, processor), distributed arrangements, end-userdevices, etc. of varying sizes, shapes, and constitution.

FIG. 1 shows wireless network 100 for communication according to someembodiments. Wireless network 100 may, for example, comprise a 5Gwireless network. As appreciated by those skilled in the art, componentsappearing in FIG. 1 are likely to have related counterparts in othernetwork arrangements including, for example, cellular-style networkarrangements and non-cellular-style-network arrangements (e.g., deviceto device or peer to peer or ad hoc network arrangements, etc.).

Wireless network 100 illustrated in FIG. 1 includes a number of basestations 105 and other network entities. A base station may be a stationthat communicates with the UEs and may also be referred to as an evolvednode B (eNB), a next generation eNB (gNB), an access point, and thelike. Each base station 105 may provide communication coverage for aparticular geographic area. In 3GPP, the term “cell” can refer to thisparticular geographic coverage area of a base station and/or a basestation subsystem serving the coverage area, depending on the context inwhich the term is used. In implementations of wireless network 100herein, base stations 105 may be associated with a same operator ordifferent operators (e.g., wireless network 100 may comprise a pluralityof operator wireless networks), and may provide wireless communicationsusing one or more of the same frequencies (e.g., one or more frequencybands in licensed spectrum, unlicensed spectrum, or a combinationthereof) as a neighboring cell. In some examples, an individual basestation 105 or UE 115 may be operated by more than one network operatingentity. In other examples, each base station 105 and UE 115 may beoperated by a single network operating entity.

A base station may provide communication coverage for a macro cell or asmall cell, such as a pico cell or a femto cell, and/or other types ofcell. A macro cell generally covers a relatively large geographic area(e.g., several kilometers in radius) and may allow unrestricted accessby UEs with service subscriptions with the network provider. A smallcell, such as a pico cell, would generally cover a relatively smallergeographic area and may allow unrestricted access by UEs with servicesubscriptions with the network provider. A small cell, such as a femtocell, would also generally cover a relatively small geographic area(e.g., a home) and, in addition to unrestricted access, may also providerestricted access by UEs having an association with the femto cell(e.g., UEs in a closed subscriber group (CSG), UEs for users in thehome, and the like). A base station for a macro cell may be referred toas a macro base station. A base station for a small cell may be referredto as a small cell base station, a pico base station, a femto basestation or a home base station. In the example shown in FIG. 1, basestations 105 d and 105 e are regular macro base stations, while basestations 105 a-105 c are macro base stations enabled with one of 3dimension (3D), full dimension (FD), or massive MIMO. Base stations 105a-105 c take advantage of their higher dimension MIMO capabilities toexploit 3D beamforming in both elevation and azimuth beamforming toincrease coverage and capacity. Base station 105 f is a small cell basestation which may be a home node or portable access point. A basestation may support one or multiple (e.g., two, three, four, and thelike) cells.

Wireless network 100 may support synchronous or asynchronous operation.For synchronous operation, the base stations may have similar frametiming, and transmissions from different base stations may beapproximately aligned in time. For asynchronous operation, the basestations may have different frame timing, and transmissions fromdifferent base stations may not be aligned in time. In some scenarios,networks may be enabled or configured to handle dynamic switchingbetween synchronous or asynchronous operations.

UEs 115 are dispersed throughout the wireless network 100, and each UEmay be stationary or mobile. It should be appreciated that, although amobile apparatus is commonly referred to as user equipment (UE) instandards and specifications promulgated by the 3rd GenerationPartnership Project (3GPP), such apparatus may also be referred to bythose skilled in the art as a mobile station (MS), a subscriber station,a mobile unit, a subscriber unit, a wireless unit, a remote unit, amobile device, a wireless device, a wireless communications device, aremote device, a mobile subscriber station, an access terminal (AT), amobile terminal, a wireless terminal, a remote terminal, a handset, aterminal, a user agent, a mobile client, a client, or some othersuitable terminology. Within the present document, a “mobile” apparatusor UE need not necessarily have a capability to move, and may bestationary. Some non-limiting examples of a mobile apparatus, such asmay comprise embodiments of one or more of UEs 115, include a mobile, acellular (cell) phone, a smart phone, a session initiation protocol(SIP) phone, a wireless local loop (WLL) station, a laptop, a personalcomputer (PC), a notebook, a netbook, a smart book, a tablet, and apersonal digital assistant (PDA). A mobile apparatus may additionally bean “Internet of things” (IoT) or “Internet of everything” (IoE) devicesuch as an automotive or other transportation vehicle, a satelliteradio, a global positioning system (GPS) device, a logistics controller,a drone, a multi-copter, a quad-copter, a smart energy or securitydevice, a solar panel or solar array, municipal lighting, water, orother infrastructure; industrial automation and enterprise devices;consumer and wearable devices, such as eyewear, a wearable camera, asmart watch, a health or fitness tracker, a mammal implantable device,gesture tracking device, medical device, a digital audio player (e.g.,MP3 player), a camera, a game console, etc.; and digital home or smarthome devices such as a home audio, video, and multimedia device, anappliance, a sensor, a vending machine, intelligent lighting, a homesecurity system, a smart meter, etc. In one aspect, a UE may be a devicethat includes a Universal Integrated Circuit Card (UICC). In anotheraspect, a UE may be a device that does not include a UICC. In someaspects, UEs that do not include UICCs may also be referred to as IoEdevices. UEs 115 a-115 d of the embodiment illustrated in FIG. 1 areexamples of mobile smart phone-type devices accessing wireless network100 A UE may also be a machine specifically configured for connectedcommunication, including machine type communication (MTC), enhanced MTC(eMTC), narrowband IoT (NB-IoT) and the like. UEs 115 e-115 killustrated in FIG. 1 are examples of various machines configured forcommunication that access wireless network 100.

A mobile apparatus, such as UEs 115, may be able to communicate with anytype of the base stations, whether macro base stations, pico basestations, femto base stations, relays, and the like. In FIG. 1, alightning bolt (e.g., communication link) indicates wirelesstransmissions between a UE and a serving base station, which is a basestation designated to serve the UE on the downlink and/or uplink, ordesired transmission between base stations, and backhaul transmissionsbetween base stations. Backhaul communication between base stations ofwireless network 100 may occur using wired and/or wireless communicationlinks.

In operation at wireless network 100, base stations 105 a-105 c serveUEs 115 a and 115 b using 3D beamforming and coordinated spatialtechniques, such as coordinated multipoint (CoMP) or multi-connectivity.Macro base station 105 d performs backhaul communications with basestations 105 a-105 c, as well as small cell, base station 105 f. Macrobase station 105 d also transmits multicast services which aresubscribed to and received by UEs 115 c and 115 d. Such multicastservices may include mobile television or stream video, or may includeother services for providing community information, such as weatheremergencies or alerts, such as Amber alerts or gray alerts.

Wireless network 100 of embodiments supports mission criticalcommunications with ultra-reliable and redundant links for missioncritical devices, such UE 115 e, which is a drone. Redundantcommunication links with UE 115 e include from macro base stations 105 dand 105 e, as well as small cell base station 105 f. Other machine typedevices, such as UE 115 f (thermometer), UE 115 g (smart meter), and UE115 h (wearable device) may communicate through wireless network 100either directly with base stations, such as small cell base station 105f, and macro base station 105 e, or in multi-hop configurations bycommunicating with another user device which relays its information tothe network, such as UE 115 f communicating temperature measurementinformation to the smart meter, UE 115 g, which is then reported to thenetwork through small cell base station 105 f. Wireless network 100 mayalso provide additional network efficiency through dynamic, low-latencyTDD/FDD communications, such as in a vehicle-to-vehicle (V2V) meshnetwork between UEs 115 i-115 k communicating with macro base station105 e.

FIG. 2 shows a block diagram of a design of a base station 105 and a UE115, which may be any of the base stations and one of the UEs in FIG. 1.For a restricted association scenario (as mentioned above), base station105 may be small cell base station 105 f in FIG. 1, and UE 115 may be UE115 c or 115D operating in a service area of base station 105 f, whichin order to access small cell base station 105 f, would be included in alist of accessible UEs for small cell base station 105 f. Base station105 may also be a base station of some other type. As shown in FIG. 2,base station 105 may be equipped with antennas 234 a through 234 t, andUE 115 may be equipped with antennas 252 a through 252 r forfacilitating wireless communications.

At the base station 105, a transmit processor 220 may receive data froma data source 212 and control information from a controller/processor240. The control information may be for the physical broadcast channel(PBCH), physical control format indicator channel (PCFICH), physicalhybrid-ARQ (automatic repeat request) indicator channel (PHICH),physical downlink control channel (PDCCH), enhanced physical downlinkcontrol channel (EPDCCH), MTC physical downlink control channel(MPDCCH), etc. The data may be for the PDSCH, etc. The transmitprocessor 220 may process (e.g., encode and symbol map) the data andcontrol information to obtain data symbols and control symbols,respectively. The transmit processor 220 may also generate referencesymbols, e.g., for the primary synchronization signal (PSS) andsecondary synchronization signal (SSS), and cell-specific referencesignal. Transmit (TX) multiple-input multiple-output (MIMO) processor230 may perform spatial processing (e.g., precoding) on the datasymbols, the control symbols, and/or the reference symbols, ifapplicable, and may provide output symbol streams to modulators (MODs)232 a through 232 t. Each modulator 232 may process a respective outputsymbol stream (e.g., for OFDM, etc.) to obtain an output sample stream.Each modulator 232 may additionally or alternatively process (e.g.,convert to analog, amplify, filter, and upconvert) the output samplestream to obtain a downlink signal. Downlink signals from modulators 232a through 232 t may be transmitted via the antennas 234 a through 234 t,respectively.

At the UE 115, the antennas 252 a through 252 r may receive the downlinksignals from the base station 105 and may provide received signals tothe demodulators (DEMODs) 254 a through 254 r, respectively. Eachdemodulator 254 may condition (e.g., filter, amplify, downconvert, anddigitize) a respective received signal to obtain input samples. Eachdemodulator 254 may further process the input samples (e.g., for OFDM,etc.) to obtain received symbols. MIMO detector 256 may obtain receivedsymbols from demodulators 254 a through 254 r, perform MIMO detection onthe received symbols if applicable, and provide detected symbols.Receive processor 258 may process (e.g., demodulate, deinterleave, anddecode) the detected symbols, provide decoded data for the UE 115 to adata sink 260, and provide decoded control information to acontroller/processor 280.

On the uplink, at the UE 115, a transmit processor 264 may receive andprocess data (e.g., for the physical uplink shared channel (PUSCH)) froma data source 262 and control information (e.g., for the physical uplinkcontrol channel (PUCCH)) from the controller/processor 280. Transmitprocessor 264 may also generate reference symbols for a referencesignal. The symbols from the transmit processor 264 may be precoded byTX MIMO processor 266 if applicable, further processed by the modulators254 a through 254 r (e.g., for SC-FDM, etc.), and transmitted to thebase station 105. At base station 105, the uplink signals from UE 115may be received by antennas 234, processed by demodulators 232, detectedby MIMO detector 236 if applicable, and further processed by receiveprocessor 238 to obtain decoded data and control information sent by UE115. Processor 238 may provide the decoded data to data sink 239 and thedecoded control information to controller/processor 240.

Controllers/processors 240 and 280 may direct the operation at basestation 105 and UE 115, respectively. Controller/processor 240 and/orother processors and modules at base station 105 and/orcontroller/processor 28 and/or other processors and modules at UE 115may perform or direct the execution of various processes for thetechniques described herein, such as to perform or direct the executionillustrated in FIGS. 9 and 10, and/or other processes for the techniquesdescribed herein. Memories 242 and 282 may store data and program codesfor base station 105 and UE 115, respectively. Scheduler 244 mayschedule UEs for data transmission on the downlink and/or uplink.

Wireless communications systems operated by different network operatingentities (e.g., network operators) may share spectrum. In someinstances, a network operating entity may be configured to use anentirety of a designated shared spectrum for at least a period of timebefore another network operating entity uses the entirety of thedesignated shared spectrum for a different period of time. Thus, inorder to allow network operating entities use of the full designatedshared spectrum, and in order to mitigate interfering communicationsbetween the different network operating entities, certain resources(e.g., time) may be partitioned and allocated to the different networkoperating entities for certain types of communication.

For example, a network operating entity may be allocated certain timeresources reserved for exclusive communication by the network operatingentity using the entirety of the shared spectrum. The network operatingentity may also be allocated other time resources where the entity isgiven priority over other network operating entities to communicateusing the shared spectrum. These time resources, prioritized for use bythe network operating entity, may be utilized by other network operatingentities on an opportunistic basis if the prioritized network operatingentity does not utilize the resources. Additional time resources may beallocated for any network operator to use on an opportunistic basis.

Access to the shared spectrum and the arbitration of time resourcesamong different network operating entities may be centrally controlledby a separate entity, autonomously determined by a predefinedarbitration scheme, or dynamically determined based on interactionsbetween wireless nodes of the network operators.

In some cases, UE 115 and base station 105 may operate in a shared radiofrequency spectrum band, which may include licensed or unlicensed (e.g.,contention-based) frequency spectrum. In an unlicensed frequency portionof the shared radio frequency spectrum band, UEs 115 or base stations105 may traditionally perform a medium-sensing procedure to contend foraccess to the frequency spectrum. For example, UE 115 or base station105 may perform a listen before talk (LBT) procedure such as a clearchannel assessment (CCA) prior to communicating in order to determinewhether the shared channel is available. A CCA may include an energydetection procedure to determine whether there are any other activetransmissions. For example, a device may infer that a change in areceived signal strength indicator (RSSI) of a power meter indicatesthat a channel is occupied. Specifically, signal power that isconcentrated in a certain bandwidth and exceeds a predetermined noisefloor may indicate another wireless transmitter. A CCA also may includedetection of specific sequences that indicate use of the channel. Forexample, another device may transmit a specific preamble prior totransmitting a data sequence. In some cases, an LBT procedure mayinclude a wireless node adjusting its own backoff window based on theamount of energy detected on a channel and/or theacknowledge/negative-acknowledge (ACK/NACK) feedback for its owntransmitted packets as a proxy for collisions.

FIG. 3 illustrates an example of a wireless communications system 300that supports single message cross carrier activation or reactivation inaccordance with aspects of the present disclosure. To illustrate, asingle periodic grant, such as downlink control message (e.g., downlinkcontrol information (DCI) message) or semi-persistent scheduling (SPS)message, on one carrier (e.g., channel or component carrier (CC)) canactivate or reactivate periodic grant (e.g., SPS scheduling) on multiplechannels or CCs. That is configured grants (CGs) may be scheduled formultiple types of transmissions for multiple CCs. For example, CGs forPDSCHs can be scheduled for multiple CCs for one or more subsequentcycles based on the single message indicating a periodic grant.

In some examples, wireless communications system 300 may implementaspects of wireless communication system 100. For example, wirelesscommunications system 300 may include UE 115 and base station 105.Although one UE and one base station are illustrated, in otherimplementations, wireless communications system 300 may include multipleUEs 115, multiple base stations 105, or both. Single message crosscarrier may enable reduced overhead and latency when scheduling messagesand thus may increase throughput. Cross carrier repetition may furtherbe utilized to increase reliability, and possibly throughput wheninterference or blockage is present on or more carriers (e.g., channelsor CCs).

UE 115 includes processor 302, memory 304, transmitter 310, receiver312, and channel measurement circuitry 314. Processor 302 may beconfigured to execute instructions stored at memory 304 to perform theoperations described herein. In some implementations, processor 302includes or corresponds to controller/processor 280, and memory 304includes or corresponds to memory 282. Memory 304 may also be configuredto store a table 306, SPS configurations 308, first CGs 352, second CGs354, or a combination thereof, as further described herein.

The table 306 may include or correspond to a table (e.g., a mappingtable) to which indicates one or more SPS configurations 308 based on across carrier activation indicator, such as cross carrier activationindicator 362. Each SPS configuration of the one or more SPSconfigurations 308 includes scheduling information and/or transmissioninformation for scheduling CGs, such as first CGs 352, second CGs 354,or both. To illustrate, the scheduling information may include when andwhere the CGs are located in a next cycle. As another illustration, thetransmission information may include the transmission and/or receptioncharacteristics for transmitting/receiving the CGs, such as BWP ID, beamsweep enabled, beam sweep pattern, etc.

Transmitter 310 is configured to transmit data to one or more otherdevices, and receiver 312 is configured to receive data from one or moreother devices. For example, transmitter 310 may transmit data, andreceiver 312 may receive data, via a network, such as a wired network, awireless network, or a combination thereof. For example, UE 115 may beconfigured to transmit and/or receive data via a direct device-to-deviceconnection, a local area network (LAN), a wide area network (WAN), amodem-to-modem connection, the Internet, intranet, extranet, cabletransmission system, cellular communication network, any combination ofthe above, or any other communications network now known or laterdeveloped within which permits two or more electronic devices tocommunicate. In some implementations, transmitter 310 and receiver 312may be replaced with a transceiver. Additionally, or alternatively,transmitter 310, receiver, 312, or both may include or correspond to oneor more components of UE 115 described with reference to FIG. 2.

Cross carrier activation circuitry 314 is configured to perform one ormore cross carrier operations described herein, such as controlactivation or reactivation of SPS CGs, generation of CGs (e.g., 352,354), processing of cross carrier activation indicators (e.g., 362),generating second cross carrier activation indicators (e.g., 372), or acombination thereof. A second cross carrier activation indicator (e.g.,372) may acknowledge receipt and successful decode of a cross carrieractivation indicator (e.g., 362). Although illustrated as separate fromprocessor 302, transmitter 310, and receiver 312, cross carrieractivation circuitry 314 may include or correspond to such components.

Base station 105 includes processor 330, memory 332, transmitter 334,and receiver 336. Processor 330 may be configured to executeinstructions stores at memory 332 to perform the operations describedherein. In some implementations, processor 330 includes or correspondsto controller/processor 240, and memory 332 includes or corresponds tomemory 242. Memory 332 may be configured to store a table 306, SPSconfigurations 308, first CGs 352, second CGs 354, or a combinationthereof, similar to the UE 115 and as further described herein.

Transmitter 334 is configured to transmit data to one or more otherdevices, and receiver 336 is configured to receive data from one or moreother devices. For example, transmitter 334 may transmit data, andreceiver 336 may receive data, via a network, such as a wired network, awireless network, or a combination thereof. For example, base station105 may be configured to transmit and/or receive data via a directdevice-to-device connection, a local area network (LAN), a wide areanetwork (WAN), a modem-to-modem connection, the Internet, intranet,extranet, cable transmission system, cellular communication network, anycombination of the above, or any other communications network now knownor later developed within which permits two or more electronic devicesto communicate. In some implementations, transmitter 334 and receiver336 may be replaced with a transceiver. Additionally, or alternatively,transmitter 334, receiver, 336, or both may include or correspond to oneor more components of base station 105 described with reference to FIG.2.

During operation of wireless communications system 300, a first message320 is transmitted by the base station 105 via a first carrier (e.g., afirst channel or a first component carrier (CC)) of a plurality ofcarriers. As illustrated in FIG. 1, the first message 320 includes across carrier activation indicator 362. Cross carrier activationindicator 362 may indicate activation or reactivation of a periodicgrant, such as an SPS. Alternatively, the first message 320 may indicateactivation or reactivation of a periodic grant, such as an SPS. Toillustrated, the first message 320, such as DCI, may be an SPSactivation message or an SPS reactivation message. Based on the crosscarrier activation indicator 362 of the first message 320, the UE 115initiates scheduling of one or more CGs for multiple channels or CCs.For example, the UE 115 (e.g., 314 thereof) determines a particular SPSconfiguration of the SPS configurations 308 based on table 306. Toillustrate, the cross carrier activation indicator 362 may be a singlebit or bitmap (multiple bits), and the UE 115 may determine the SPSconfiguration by using table 306.

The UE 115 schedules first CGs 352, second CGs 354 based on thedetermined SPS configuration indicated by the cross carrier activationindicator 362 directly (e.g., information on schedule and transmissionis included the message) or indirectly (e.g., settings are identified bythe cross carrier activation indicator 362 using table 306). The CGs maycorrespond to any type of transmission. As illustrated in FIG. 3, the CGscheduled is for a downlink transmission, such as PDSCH. Based onscheduling the CGs, the UE monitors the scheduling CGs for reception oftransmissions.

In some implementations, the first message 320 further includes a beamsweep indicator 364. The beam sweep indicator 364 may indicate that beamsweep is enabled, a particular beam sweep pattern for the CGs, or both.In a particular implementation, a single bit or field of the firstmessage 320 indicates both cross carrier activation and beam sweep,i.e., functions as both 362 and 364. In other implementations, the beamsweep indicator 364 is included in another message (e.g., anothermessage similar to first message 320) transmitted on a second carrier.The other message then enables beam sweep for the CGs scheduled from thefirst message 320.

Additionally, the UE may transmit a response message to base station 105in response to the first message 320. For example, the UE may transmit asecond message 322 (e.g., an acknowledgment message). As the UEsuccessfully decoded the first message 320, the UE may transmit anpositive acknowledgment (e.g., ACK). A second cross carrier activationindicator 372 may be included in the second message 322 (e.g., anacknowledgment message) in some implementations to acknowledge receiptand successful decode of the cross carrier activation indicator 362 ofthe first message 320 to the base station 105.

Although not shown in FIG. 3, the base station 105 may send multiplefirst message 320 in multiple CCs, as described and shown with referenceto later figures. Such messages may be the same (repetitions) and may beincluded to improve reliability. Although, as described herein, the UE115 only has to decode one first message 320 transmitted via onechannel/CC to enable SPS on multiple channels/CC.

The base station 105 transmits third messages 340 according to the SPSCGs indicated or identified by the cross carrier activation indicator362 of first message 320. Each third message 340 may be transmitted onits own carrier, such as channel/CC. In some implementations, the thirdmessages 340 are identical, i.e., have the same settings and same data.In other implementations, one or more third messages of the thirdmessages 340 may be different, e.g., have different transmissionsettings or different data, such as different payload data. UE 115monitors the SPS CGs and receives the third messages 340 on multiplecarriers. The UE 115 may decode the third messages 340 individually orjointly. The previously described operation corresponds to downlink SPSCGs. UE 115, in addition to or in the alternative of, may perform SPSCGs for uplink transmissions.

Thus, FIG. 3 describes single message activation or reactivation of SPSCGs between UE 115 and base station 105. Single message activation orreactivation of SPS CGs enables a network to reduce latency and overheadand improve reliability, as compared to having a message on each channelor CC activate/reactivate its own channel or CC for SPS CGs. Improvingperformance of such operations may improve throughput for communicationson the network and enable use of mm wave frequency ranges and URLLCmodes.

FIGS. 4-8 illustrate examples of SPS (e.g., a type of periodic grant).FIG. 4 illustrates an example of SPS activation per CC. FIG. 5illustrates an example of SPS reactivation per CC. FIGS. 6-8 illustrateexamples of single message periodic grant activation. FIG. 6 illustratesan example of single message SPS activation or reactivation of multipleCCs. FIG. 7 illustrates another example of single message SPS activationor reactivation of multiple CCs with beam sweep. FIG. 8 illustrates anexample of single message SPS activation or reactivation of multiple CCswith two different CG configurations.

Referring to FIG. 4, FIG. 4 illustrates a timing diagram 400illustrating communications between a base station 402 and a UE 404.Base station 402 may direct the UE 404 to activate each CC individuallywith its own dedicated SPS activation message. However, if an SPSactivation message is not successfully received and decoded (asillustrated in FIG. 5), the transmission of data on one or more CCs willbe delayed. To illustrate, short cycle times (e.g., low latency modes),signal blockage, interference, slot configuration, etc. may affect aUE's ability to decode the SPS activation message and/or provide anacknowledgment thereof in the same cycle. As an example, URLLC mayoperate in the mm wave frequency range, which is more prone to blockage,and may operate with low latency such that SPS message acknowledgmentsare generally provided in the next cycle.

Referring to timing diagram 400, multiple cycles (first cycle 412,second cycle 414, and third cycle 416) are illustrated for a singlefrequency range (e.g., FR1 or FR2), a frequency range 422 (e.g., firstfrequency range). As illustrated in FIG. 4, the frequency range 422 isFR2 and has a sub carrier spacing (SCS) of 120. Also, two componentcarriers (CCs) are illustrated for the frequency range 422.Specifically, the frequency range 422 has a first CC 432 (e.g., CC 7)and a second CC 434 (e.g., CC 0).

In FIG. 4, the base station 402 transmits a SPS activation message 442(e.g., first SPS activation message) via the first CC 432 (e.g., a firstcarrier) and transmits a SPS activation message 444 (e.g., second SPSactivation message) via the second CC 434. The SPS activation messages442, 444 may be acknowledged by corresponding acknowledgment messages,such as by positive ACKs in PUCCHs (not shown but similar to PUCCHs 456,458). Based on the receipt and transmission of SPS activation messages442, 444 (and optionally corresponding acknowledgment messages) the UE404 and base station 402 may schedule CGs for future cycles, such ascycles 414, 416.

In the example of FIG. 4, the UE 404 and the base station 402 scheduleCGs for PDSCHs in cycles 414 and 416. Specifically, the UE schedules CGsof PDSCH 452 (e.g., first PDSCH) and PDSCH 462 (e.g., third PDSCH) basedon SPS activation message 442 (e.g., first SPS activation message), andthe UE schedules CGs of PDSCH 454 (e.g., second PDSCH) and PDSCH 464(e.g., fourth PDSCH) based on SPS activation message 444 (e.g., secondSPS activation message). The UE 404 may transmit acknowledgment messagesfor the PDSCHs. As illustrated in FIG. 4, the UE 404 transmitsacknowledgment messages for PDSCHs 452, 454 in corresponding PUCCHs 456,458.

Referring to FIG. 5, FIG. 5 illustrates a timing diagram 500illustrating communications between a base station 502 and a UE 504.Base station 502 may direct the UE 504 to activate each CC individuallywith its own dedicated SPS activation or reactivation message. However,if a SPS activation or reactivation message is not successfully receivedand decoded as illustrated in FIG. 5 and described above with referenceto FIG. 4, CGs may be delayed and a common target update time may bedelayed. As illustrated in FIG. 5, the SPS messages are reactivationmessages and the SPS of FIG. 4 may be reactivated as depicted in FIG. 5.

Referring to timing diagram 500, multiple cycles (first cycle 512,second cycle 514, and third cycle 516) are illustrated for a singlefrequency range (e.g., FR1 or FR2), a frequency range 522 (e.g., firstfrequency range). As illustrated in FIG. 5, the frequency range 522 isFR2 and has a sub carrier spacing (SCS) of 120. Also, two componentcarriers (CCs) are illustrated for the frequency range 522.Specifically, the frequency range 522 has a first CC 532 (e.g., CC 7)and a second CC 534 (e.g., CC 0).

In FIG. 5, the base station 502 transmits a SPS reactivation message 542(e.g., first SPS reactivation message) via the first CC 532 andtransmits a SPS reactivation message 544 (e.g., second SPS reactivationmessage) via the second CC 534. In FIG. 5, the UE 504 does notsuccessfully receive and/or decode the SPS reactivation message 542.Thus, the UE transmits a NACK 546 corresponding to SPS reactivationmessage 542 in the first CC 532 and a ACK 548 corresponding to SPSreactivation message 544 in the second CC 534.

Because of the failed SPS reactivation on the first CC 532, the basestation transmits another SPS reactivation message 556 via the first CC532 in the second cycle 514, which is successfully received and decoded,and acknowledged via ACK in PUCCH 558. Although PDSCHs 552 and 554 maybe scheduled, if they are scheduled, they may not be useable for PDSCHcross carrier repetition.

In the example of FIG. 5, the UE 504 and the base station 502 scheduleCGs for PDSCHs in both CCs for cycle 516 only. Specifically, the UEschedules a CG of PDSCH 562 (e.g., third PDSCH) based on SPSreactivation message 556 (e.g., third SPS reactivation message), and theUE schedules a CG of PDSCH 564 (e.g., fourth PDSCH) based on SPSreactivation message 544 (e.g., second SPS reactivation message). SuchCGs of PDSCHs 562 and 564 may be cross carrier PDSCH repetitions.Accordingly, such repetitions of the third cycle 516 may be jointlydecoded to increase throughput and reliability. The UE may transmitacknowledgment messages for the PDSCHs similar to as described withreference to FIG. 4.

Referring to FIG. 6, FIG. 6 illustrates a timing diagram 600illustrating communications between a base station 602 and a UE 604.Base station 602 may activate or reactivate SPS CGs for the UE 604across multiple CCs with a single SPS message. Thus, the UE can onlydecode one SPS message in one CC to activate or reactivate SPS CGsacross multiple CCs. Accordingly, SPS CGs may be configured faster withreduced latency across multiple CCs as compared to per CC activation inFIGS. 4 and 5. In the example illustrated in FIG. 6, the UE operates inwithout beam sweep enabled.

Referring to timing diagram 600, multiple cycles (first cycle 612,second cycle 614, and third cycle 616) are illustrated for a singlefrequency range (e.g., FR1 or FR2), a frequency range 622 (e.g., firstfrequency range). As illustrated in FIG. 6, the frequency range 622 isFR2 and has a sub carrier spacing (SCS) of 120. Also, two componentcarriers (CCs) are illustrated for the frequency range 622.Specifically, the frequency range 622 has a first CC 632 (e.g., CC 7)and a second CC 634 (e.g., CC 0). Although reactivation messages areillustrated in FIG. 6, in other implementations, activation message maybe transmitted.

During operation, the base station 602 transmits a SPS message 642(e.g., first SPS activation or reactivation message) via the first CC632 and transmits a SPS message 644 (e.g., second SPS activation orreactivation message) via the second CC 634. In FIG. 6, the UE 604 doesnot successfully receive and/or decode the SPS message 642. Thus, the UE604 transmits a NACK 646 corresponding to SPS message 642 in the firstCC 632 and a ACK 648 corresponding to SPS message 644 in the second CC634. The NACK 646 and ACK 648 may be transmitted in correspondingPUCCHs, such as a UCI thereof.

In the example of FIG. 6, the UE 604 and the base station 602 scheduleCGs for PDSCHs in cycles 614 and 616. Specifically, the UE 604 schedulesCGs of PDSCHs 652 (e.g., first PDSCH), PDSCH 654 (e.g., second PDSCH),PDSCH 662 (e.g., third PDSCH), and PDSCH 664 (e.g., fourth PDSCH) basedon SPS message 644 (e.g., second SPS message). UE 604 may determine toactivate SPS CGs for multiple CCs based on a cross carrier activationindicator (e.g., 362) included in SPS message 644. As compared to FIG. 5where one SPS message is not received, the common target update time inFIG. 6 (time to activate all SPS/CGs on multiple or all CCs) is reducedby one cycle reducing latency and improving throughput. Accordingly,PDSCH cross carrier repetition may be initiated one cycle earlier and bya single message.

The UE 604 may send acknowledgment messages for the PDSCHs scheduled byconfigured grant. As illustrated in FIG. 6, UE 604 transmitscorresponding acknowledgment messages for PDSCHs 652, 654 via PUCCHs656, 658.

Although two cycles of CGs are illustrated in FIG. 6, in otherimplementations, the UE 604 and base station 602 may continue toschedule CGs for additional cycles, such as X number of cycles. Theamount of cycles may be preprogramed or reconfigurable. As illustrative,non-limiting examples, 2, 3, 4, 5, 6, 7, 10, etc., cycles may be usedfor X.

Referring to FIG. 7, FIG. 7 illustrates a timing diagram 700illustrating communications between a base station 702 and a UE 704.Base station 702 may direct the UE 704 to operate with beam sweep, suchas identify or provide beam sweep pattern information for CGs acrossmultiple CCs scheduled by a single SPS message. Base station 702 mayenable cross carrier activation (e.g., cross carrier repetition) with afirst message and beam sweep with a second message, or may enable bothcross carrier activation (e.g., cross carrier repetition) and beam sweepwith a single message.

Referring to timing diagram 700, multiple cycles (first cycle 712,second cycle 714, and third cycle 716) are illustrated for a singlefrequency range (e.g., FR1 or FR2), a frequency range 722 (e.g., firstfrequency range). As illustrated in FIG. 7, the frequency range 722 isFR2 and has a sub carrier spacing (SCS) of 120. Also, two componentcarriers (CCs) are illustrated for the frequency range 722.Specifically, the frequency range 722 has a first CC 732 (e.g., CC 7)and a second CC 734 (e.g., CC 0). Although reactivation messages areillustrated in FIG. 7, in other implementations, activation message maybe transmitted.

During operation, the base station 702 transmits a SPS message 742(e.g., first SPS activation or reactivation message) via the first CC732 and transmits a SPS message 744 (e.g., second SPS activation orreactivation message) via the second CC 734. In FIG. 7, the UE 704 maynot successfully receive and/or decode the SPS message 742. Thus, the UE704 transmits an ACK or a NACK corresponding to SPS message 742 in thefirst CC 732 and an ACK corresponding to SPS message 744, which wassuccessfully received and/or decoded, in the second CC 734. The ACK/NACKand ACK may be transmitted in corresponding PUCCHs, such as a UCIthereof, as described with reference to FIG. 6.

In the example of FIG. 7, the UE 704 and the base station 702 scheduleCGs for PDSCHs in cycles 714 and 716. Specifically, the UE 704 schedulesCGs of PDSCHs 752-758 (e.g., first-fourth PDSCHs) and PDSCHs 762-768(e.g., fifth-eighth PDSCHs) based on SPS message 744 (e.g., second SPSmessage). Thus, UE 704 may determine to activate SPS CGs for multipleCCs based on a cross carrier activation indicator (e.g., 362) includedin SPS message 744. As compared to FIG. 5 where one SPS message is notreceived, the common target update time in FIG. 7 (time to activate allSPS/CGs on multiple or all CCs) is reduced by one cycle reducing latencyand improving throughput.

The UE may send acknowledgment messages for the PDSCHs scheduled bySPS/configured grant. As illustrated in FIG. 7, UE 704 transmitscorresponding acknowledgment messages for PDSCHs 752-758 via PUCCHs 782,784. As shown by 760, PDSCHs 752 and 754 have the same configuration andPDSCHs 756 and 758 have the same configuration, thus, the pairs ofPDSCHs may be jointly decoded in some implementations.

In another implementation, a single SPS message (e.g., 744) enables bothSPS and beam sweep. For example, SPS message 742 may be not besuccessfully received or decoded, and SPS message 744 may indicate beamsweep in addition to cross carrier activation (e.g., cross carrierrepetition). To illustrate, SPS message 744 further includes a beamsweep indicator. The beam sweep indicator may be a dedicated indicator(e.g., 372) or included in or part of the cross carrier indicator (e.g.,362) of SPS message 744.

Thus, FIG. 7 describes a beam sweep mode where the UE can determine beamsweep pattern based on a single message, e.g., the same message thatindicates cross carrier activation or another single message.Accordingly, the UE and the base station can obtain the benefits of beamsweep, such as reduced latency overhead and increased throughput andreliability, with reduced overhead and signaling.

Referring to FIG. 8, FIG. 8 illustrates a timing diagram 800illustrating communications between a base station 802 and a UE 804.Base station 802 may direct the UE 804 to operate with differentcharacteristics in subsets of carriers of the plurality of carriers by asingle SPS message. As illustrated in FIG. 8, at least one CC has adifferent beam sweep. Base station 802 may enable a first cross carrieractivation (e.g., cross carrier repetition) with a first message and asecond cross carrier activation with a second message, or may enableboth cross carrier activations (e.g., cross carrier repetition) with asingle message.

Referring to timing diagram 800, multiple cycles (first cycle 812,second cycle 814, and third cycle 816) are illustrated for a singlefrequency range (e.g., FR1 or FR2), a frequency range 822 (e.g., firstfrequency range). As illustrated in FIG. 8, the frequency range 822 isFR2 and has a sub carrier spacing (SCS) of 120. Also, three componentcarriers (CCs) are illustrated for the frequency range 822.Specifically, the frequency range 822 has a first CC 832 (e.g., CC 8), asecond CC 834 (e.g., CC 1), and a third CC 836 (e.g., CC 0). Althoughreactivation messages are illustrated in FIG. 8, in otherimplementations, activation message may be transmitted.

During operation, the base station 802 transmits a SPS message 842(e.g., first SPS activation or reactivation message) via the first CC832, transmits a SPS message 844 (e.g., second SPS activation orreactivation message) via the second CC 834, and transmits a SPS message846 (e.g., third SPS activation or reactivation message) via the thirdCC 836. In FIG. 8, the UE 804 does not successfully receive and/ordecode the SPS message 842. Thus, the UE 804 transmits a NACK 852corresponding to SPS message 842 in the first CC 832 and ACKs 854, 856corresponding to SPS messages 844, 846 in the second CC 834 and thethird CC 836 as illustrated. The NACK 852 and ACKs 854, 856 may betransmitted in corresponding PUCCHs, such as a UCI thereof.

In the example of FIG. 8, the UE 804 and the base station 802 scheduleCGs for PDSCHs in cycles 814 and 816. Specifically, the UE 804 schedulesCGs of PDSCHs 862 (e.g., first PDSCH), PDSCH 864 (e.g., second PDSCH),PDSCH 866 (e.g., third PDSCH), PDSCH 872 (e.g., fourth PDSCH), PDSCH 874(e.g., fifth PDSCH), and PDSCH 876 (e.g., sixth PDSCH) based on SPSmessage 844 (e.g., second SPS message alone). UE 804 may determine toactivate SPS CGs for multiple CCs based on a cross carrier activationindicator (e.g., 362) included in SPS message 844. As shown by 868,PDSCHs have the same configuration, thus, the may be jointly decoded insome implementations. As compared to FIG. 5 where one SPS message is notreceived, the common target update time in FIG. 8 (time to activate allSPS/CGs on multiple or all CCs) is reduced by one cycle reducing latencyand improving throughput.

In other implementations, UE schedules CGs of PDSCHs 866 (e.g., thirdPDSCH), and PDSCH 876 (e.g., sixth PDSCH) based on SPS message 846(e.g., third SPS message alone and not SPS message 844). Thus, UE 804may schedule multiple different types of CGs across the CCs based one ormore SPS messages (e.g., 844, or 844 and 846).

Although the CCs are included in a single frequency range in FIGS. 4-8,in other implementations the CCs may be included in multiple frequencyranges, such as FR1 and FR2. Additionally, or alternatively, asillustrated in FIG. 8, the CCs may be split into groups (e.g., QCLgroups or groups having same QCL) in one or more frequency ranges.

Furthermore, in any of single message SPS cross carrier activationexamples of FIGS. 6-8, the UE can still operate in a per channelactivation mode for one or more channels, as in FIGS. 4 and 5. Forexample, the UE can still activate one or more carriers (e.g., CCs)individually, such as dedicated control carriers, uplink carriers,downlink carriers, etc., as illustrative, non-limiting examples.Accordingly, the cross carrier activation operations described hereinoffer more flexibility with reduced overhead and enable cross carrierrepetition and beam sweep to be activated more quickly, such as forshort cycle durations, which may be present in 5G and/or URLLC modes.

FIG. 9 is a block diagram illustrating example blocks executed by a UEconfigured according to an aspect of the present disclosure. The exampleblocks will also be described with respect to UE 115 as illustrated inFIG. 11. FIG. 11 is a block diagram illustrating UE 115 configuredaccording to one aspect of the present disclosure. UE 115 includes thestructure, hardware, and components as illustrated for UE 115 of FIG. 2.For example, UE 115 includes controller/processor 280, which operates toexecute logic or computer instructions stored in memory 282, as well ascontrolling the components of UE 115 that provide the features andfunctionality of UE 115. UE 115, under control of controller/processor280, transmits and receives signals via wireless radios 1100 a-r andantennas 252 a-r.

At block 900, a mobile communication device, such as a UE receives,during a first cycle, a periodic grant via a first carrier of aplurality of carriers. A UE, such as UE 115, may execute, under controlof controller/processor 280, cross carrier activation logic 1102, storedin memory 282. The execution environment of cross carrier activationlogic 1102 provides the functionality for UE 115 to define and performthe cross carrier activation procedures. The execution environment ofcross carrier activation logic 1102 defines the different cross carrieractivation processes, such as determining SPS configurations (e.g., 308)configured grant scheduling (e.g., 352, 354) using one or more of1104-1108, as described with reference to block 901. UE 115 receives theperiodic grant (e.g., a downlink message) via antennas 252 a-r andwireless radios 1100 a-r. UE may send an acknowledgement messageresponsive to the periodic grant to indicate successful reception anddecoding of the periodic grant.

At block 901, the UE monitors, during a next cycle after the firstcycle, for configured grants (CGs) for multiple carriers of theplurality of carriers based on the periodic grant, during monitoring,one or more channel measurements for a set of candidate CCs of theplurality of CCs. The execution environment of cross carrier activationlogic 1102 provides UE 115 the functionalities described with respect tothe various aspects of the present disclosure, such as determining SPSconfigurations (e.g., 308) configured grant scheduling (e.g., 352, 354)using one or more of 1104-1108. To illustrate, within the executionenvironment of cross carrier activation logic 1102, UE 115, undercontrol of controller/processor 280, may determine one or more SPSconfigurations for CGs based on table 1104. As an illustrative example,table 1104 is a mapping table which maps information indicated by across carrier indicator (e.g., 362) to one or more SPS configurationsfor CGs of the possible SPS configurations 1106 and CGs 1108.

At block 902, the UE receives, during the next cycle after the firstcycle, a first transmission in a first CG of the CGs via a secondcarrier of the plurality of carriers and a second transmission in asecond CG of the CGs via a third carrier of the plurality of carriers.Once UE 115 determines the schedule of CGs and SPS configuration atblock 901, UE 115 may monitor the CGs and receive transmissionscorresponding to the CGs scheduled by the single periodic grant messagevia wireless radios 1100 a-r and antennas 252 a-r.
